undefined method `load_file' for Psych:Module (NoMethodError)

[jwithington]

Hello! First off, thanks for making t! It's awesome.

Recently, though, something's been up and I haven't been able to get it to work. I tried installing/uninstalling.

Here's the code that I'm getting:

~/.rbenv/versions/2.1.3/lib/ruby/gems/2.1.0/gems/t-2.9.0/lib/t/rcfile.rb:80:inload_file': undefined method load_file' for Psych:Module (NoMethodError) from ~/.rbenv/versions/2.1.3/lib/ruby/gems/2.1.0/gems/t-2.9.0/lib/t/rcfile.rb:11:ininitialize'

from ~/.rbenv/versions/2.1.3/bin/t:23:in <main>'

Now, I switched my global rbenv to 1.9.3p547, and then it seemed to work. Is it simply not working for 2.1.3?

Thanks so much!

Hello, I had the same issue earlier today.

My ruby version is ruby 2.1.5p273 (2014-11-13 revision 48405) [x86_64-darwin13.0]

On the otehr hand, I had psych (2.0.13, 2.0.5) installed.

I removed 2.0.13 and everything went back to normal.

[avellable]

I had to remove psych at all(2.0.8,2.0.12,2.0.13) to make it work.

I get this error often as well. It goes away when I remove psych, but sooner or later psych gets reinstalled (like when I want to work on rubygems.org).
I know @sferik contributes to rubygems.org as well, wondering if you have any workarounds? 😬

[jjmanzer]

Yes I have hit this as well. Has anyone found a fix?

[techsethi]

gem uninstall psych

and it worked for me.
